I just started witg greenDao, but i can't initialize the DaoGenerator : calling new DaoGenerator(); throws the exception
java.lang.ExceptionInInitializerError
at de.greenrobot.daogenerator.DaoGenerator.(DaoGenerator.java:60)
Here is my code:
Schema schema = new Schema(1,"com.emt.testdb.greendao");
schema.setDefaultJavaPackageTest("com.emt.testdb.greendao.test");
schema.setDefaultJavaPackageDao("com.emt.testdb.greendao.dao");
Entity user = schema.addEntity("User");
user.addIdProperty();
user.addStringProperty("name");
user.addStringProperty("password");
user.addIntProperty("yearOfBirth");
DaoGenerator daoGenerator = null;
try
{
daoGenerator = new DaoGenerator();
// daoGenerator.generateAll(schema, "../project/src-gen");
} catch (IOException e)
{
e.printStackTrace();
}
catch (Exception e)
{
e.printStackTrace();
}
many thanks for your help!

I have written following code in my application:
public static final String DRIVER = "org.apache.derby.jdbc.EmbeddedDriver";
public static final String JDBC_URL = "jdbc:derby:c:/coopcashier/db/COOP;create=true";
try {
Class.forName(DRIVER);
Connection conn = DriverManager.getConnection(JDBC_URL);
Statement statement = conn.createStatement();
ResultSet resultset = statement.executeQuery("select * from USERS");
while(resultset.next()) {
if(resultset.getString(4).toString().equals(txtUsername) && resultset.getString(5).toString().equals(txtPassword)) {
homePage home = new homePage();
setVisible(false);
home.setVisible(true);
}
else {
JOptionPane.showMessageDialog(null,"Invalid Username or Password.","Invalid Credentials",JOptionPane.ERROR_MESSAGE);
}
}
if(conn != null) conn.close();
if(statement != null) statement.close();
} catch (ClassNotFoundException e1) {
e1.printStackTrace();
} catch (SQLException e2) {

When I am running this in Eclipse, everything goes well. But when I made the jar file of my project with same code and try to run, it always throw following exception:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException: Cannot invoke "java.net.URL.toExternalForm()" because "location" is null
I could not find solution. Please share if anybody resolved this problem.
TIA
i am getting this exception while i fetch data from an api that uses SOAP.
The response that i get is in Json format without an xml tag. i had also tried to parse the data using HttpResponse but it is not working...

I get "Invalid thread access" in below code. I am not sure where I have written wrong code. My main intention to write the code is to just display subtask (what is happening behind the scene) so I have added subtask before method called.

Put your progress monitor as below :
Display.getDefault().asyncExec( new Runnable()
{
IWorkbenchWindow win = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
new ProgressMonitorDialog(shell).run(true, true, new IRunnableWithProgress() {
#Override
public void run(final IProgressMonitor monitor) throws InvocationTargetException,
InterruptedException
{
monitor.beginTask("Import Data", IProgressMonitor.UNKNOWN);
monitor.subTask("Connecting to databse...");
for(int i=0;i<=100;i++)
}
If you want the workbench page, that also has to be called inside a UI thread like above.
You can't access UI code in the background thread used for the IRunnableWithProgress code.
So you must get the values of controls in the UI thread before you run the progress dialog.
You also can't access things like IWorkbenchPage in the background thread. If you want to update UI objects from a non-UI thread, you need to use Display.asyncExec or Display.syncExec to run the updating code in the UI thread.
I have a simple problem.
I want to delete a recordStore data.
when I execute the deletion code
I get this error message
javax.microedition.rms.RecordStoreException: deleteRecordStore error: record store is still open at
javax.microedition.rms.RecordStore.deleteRecordStore()
try
{
recordStore2.closeRecordStore() ;
}
catch(Exception e)
{
e.printStackTrace();
}
try
{
recordStore2.deleteRecordStore("recordStore2");
}
catch(Exception e)
{
e.printStackTrace();
}
Oh...
I have know the answer.
I should close my RecordStore into each block of code after finishing of using
it,throughout the program.
try
{
recordStore2.closeRecordStore() ;
}
catch(Exception e)
{
e.printStackTrace();
}
I have tried in many different ways to send my xml document over a socket connection between a server and a client without closing the socket after sending (keep the outputstream open, for sending another document). I have found several sites who claimed that it should work, so I tried it in all the ways they sugested, but I did not found a way which works.
(that describes the same what I would like to do: http://jaxb.java.net/guide/Designing_a_client_server_protocol_in_XML.html)
The follwing code works perfectly if I am closing the socket after sending (#code marsh.marshal(element, xsw);), but it stucks on unmarshaling on the server side, if I try to keep the socket open.
Client Side....
